Can solar energy alone satisfy electricity demands of the whole country?admin
Theoretically, photovoltaic systems could satisfy power demands of country and even the whole world. Due to the fact that the sun doesn’t shine every day and at night, one would require storage systems. No serious company can however claim that photovoltaic is the only solution to energy problems worldwide. Instead, it’s true that solar energy in form of photovoltaic and solar thermal power used in combination with other renewable energy sources (wind, geothermal, hydropower, biogas etc.) would lead to electrical power supply methods that are not only sustainable but also which go easy on resources.
